# A daily integrity check on your audit trail

> Bower now seals every audit log event into a hash chain and checks it daily, and the CSV export carries each event's chain position and stable IDs.

**2026-10-31 · Trust & compliance**

The audit log recorded every change, but nothing showed that the record itself
had not been changed. Now it does.

## What's new

* **Hash chain.** Each new event is sealed into a chain, so editing, deleting, or reordering a sealed event breaks the chain.
* **Daily check.** The audit log page shows **Audit trail verified** once
  Bower has checked your workspace's chain, or **Audit trail check failed**
  if it found a mismatch.
* **Fuller CSV export.** Each row now carries its chain position and hash,
  plus the person's and the record's IDs, so you can follow one record or one
  member across renames.
* **Deleted accounts keep their history.** When someone deletes their
  account, their events stay in the log with their identity removed, instead
  of being deleted.

See [Audit logs](https://docs.bowerlabs.ai/trust-center/audit-logs.md#integrity-check) for the details.
